question: is there an app/would there be a market for an app that i can download it to my phone and then go online and setup custom alerts when a notification should popup on my mobile dev screen? example. on my webserver at work i setup simple php page with JSON output: { monitor_param: 1 } when everything OK, or { monitor_param: 0 } when there is an issue. then i go online and setup custom alert that can reach my php script every couple minutes/seconds and check the status. IF monitor_param == 0 then push an alert on my mobile dev screen. can see multitude of places you could use it!
